Scroll and section indicator jumps if cells have different heights

[cybergen78]

The cells in my example have all equal heights except one (one label wraps and has two lines). Whenever I fast scroll over the one higher cell the scroll and the indicator flickers and jumps up and down.

One of the major limitations of of this library is that it assumes all adapter items are of equal height.

Oh noes! It's a contact name and thus can't be ellipsized. Are you planning to fix this?

Oops, I never finished writing the comment above.

I don't have a fix in mind for this issue unfortunately. As a workaround, I would suggest hardcoding the number of lines for the text view so they're all the same.

Little boxes on the hillside, Little boxes made of ticky tacky, Little boxes on the hillside, Little boxes all the same.

we can override ths method synchronizeScrollBarThumbOffsetToViewScroll and use item numbers to set the offset
